NUT OR BOLT LOCK.

SPECIFICATION forming part of Letters Patent No. 675,192, dated May 28,1901. Application filed December 5, 1900. Serial No. 38,758. (No model.)

To @all whom t may concern:

Be it known that I, WILLIAM A. BoNsAcK, a citizen of the United States,residing in the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Nut or Bolt Locks, ofwhich the following is a full, clear, and exact description, referencebeing had tothe accompanying drawings, forming part of thisspeciication.

My invention relates to locks for holding nuts and bolts from turning;and, briefly stated, it consists in a washer and lockingplate providedwith elongated openings that receive the bolts and means for securingthe locking-plate to the washer,whereby the parts are renderedadjustable with relation to the members to be held thereby.

The features of novelty will be hereinafter fully described and claimed.

Figure I is a longitudinal sectional view showing my lock applied to anut and bolt. Fig. II is a perspective view looking at the face ofthewasher. Fig. III is aperspective view of the locking-plate. Fig. IVis a rear perspective view of the washer provided with a slot for therivet that secures the lockingplate to said washer. Fig. V is alongitudinal sectional View showing a double locking means applied totwo nuts and bolts in common. Fig. VI isa perspective view of the washerused in the double lock shown in Fig. V. Fig. VII is a perspective viewof theV locking-plate used in the double lock shown in Fig. V.

1 designates abolt, and 2 a nut, of any common form.

3 designates a washer having a shoulder 4 and provided with an elongatedopening 5 for the bolt l, passed therethrough,and an elongated opening 6for a rivet 8, by which the locking-plate 10 is secured to the washerbetween the shoulder 4 and the nut or bolt-to be held. The washer 3 isalso provided with an aperture 7, that receives a fastener 9, such as ascrew, by which the washer is held in a fixed position, the fastenerbeing set into the part held by the' bolt and nut, as seen -n Fig. I.

The locking-plate 10 is provided with an elongated opening 11, thatreceives the rivet 8, inserted in the openings 6 and l1, and by whichthe locking-plate is secured to the washer 3.

In Fig. IV, I have shown the opening in the Washer 3' that receives therivet in the form of a curved slot G', 4extending to the edge of thewasher.

In practical use the lock is applied to the nut and bolt in thefollowing manner: The washer 3, with the rivet S therein, i-s rst put inposition before the bolt is inserted or the nut placed thereon, and thewasher is secured by the fastener 9. The bolt is then inserted and thenut screwed thereonto to the desired extent. The locking-plate 10 isthen put in place against the washer, so that the rivet 8 will passtherethrough, and the locking-plate being thus positioned between themembers to be held and the shoulder 4 is secured by the rivet 8. In thepositioning of the washer 3 the elongated opening 5 provides for theproper placing of the washer and obviates the necessity of perfectalinement of said openings 5 with the bolt. The elongated opening 6 inthe washer and the elongated opening 11 in the locking-plate provide forthel proper positioning of said plate, so that the plate may be adjustedto or from either the bolt-head or nut to be secured, so that thelocking-plate may be brought into firm contact with the member to beheld. This feature is of material importance, particularly where boltsand nuts of varying sizes are utilized.

In Figs. V to VII, inclusive, I have shown a double lock whereby twobolts or nuts may be held. In this form of device the washer 3a isprovided with two elongated openings 5a and two elongated openings 6u.The heads of the bolts l and nuts 2a are held by the locking-plates 10a,which are provided with elongated openings 11a, that receivesecuringrivets 8, which pass through the elongated openings 6 in thewasher. The\ opposing nuts andbolts are thereby held from turning,inasmuch as any inclination of one of them to turn is overcome by theopposing member. The washers and locking-plates being provided with theelongated openings referred to render it possible to adjust said partsin either direction in applying the lock, so that the locking-plateswill occupy the proper positions between the members held thereby.
